Prognostic correlation of NOTCH1 and SF3B1 mutations with chromosomal abnormalities in chronic lymphocytic leukemia patients.

ABSTRACT:

Background and aim

Chronic lymphocytic leukemia (CLL) is a monoclonal malignancy of B lymphocytes. Since common mutations in NOTCH1 and SF3B1, along with other possible chromosomal alterations, change disease severity and survival of patients with CLL, we aimed to evaluate the correlation of common mutations in NOTCH1 and SF3B1 as the poor prognostic markers with chromosomal abnormalities and clinical hematology.

Method

This retrospective study was performed on the peripheral blood of 51 patients diagnosed before chemotherapy with CLL. G-banding karyotype and FISH were performed. For NOTCH1, exon 34 and for SF3B1, exons 14,15,16 were assessed using Sanger sequencing.

Results

The mutation frequency of NOTCH1 and SF3B1 with the pathogenic clinical status was 6:51 (11.76
